I spent some more time on this today. And I think I found part of the answer. I don't think this is possible by using a GEF Tool. I have now a first prototype with the Drag and Drop infrastructure that does roughly what I want. When it is more improved I will write more about it here. |

As promised here the link to the commit to show how I implemented it with drag and drop: It does not feel really good but it gets the job done. If anybody has better Ideas I'm happy to hear them. |

In an application I'm working on I have the use case that I have to GEF Classic editors showing different parts of the model. And there it would make sense to allow a user to drag a connection from an element in one editor to an element in the other editor.
Is this possible in GEF classic?
I see that the Tool's mouseDrag method has the viewer as option, but this viewer is not adjusted when I leave the editor.
Therefore one option that I thought about was to chekc if the mouse is still inside the original viewer and if not try to find a viewer below the mouse position. But is this a good idea.
Looking forward to any suggestions.
